Chapter 5. Performing cross-site operations via JMX
Perform cross-site operations such as pushing state transfer and bringing sites online via JMX.
5.1. Registering JMX MBeans
Data Grid can register JMX MBeans that you can use to collect statistics and perform administrative operations. You must also enable statistics otherwise Data Grid provides 0 values for all statistic attributes in JMX MBeans.
Procedure
- Open your Data Grid configuration for editing.
-
Add the
jmxelement or object to the cache container and specifytrueas the value for theenabledattribute or field. -
Add the
domainattribute or field and specify the domain where JMX MBeans are exposed, if required. - Save and close your client configuration.
JMX configuration
XML
<infinispan>
<cache-container statistics="true">
<jmx enabled="true"
domain="example.com"/>
</cache-container>
</infinispan>
JSON
{
"infinispan" : {
"cache-container" : {
"statistics" : "true",
"jmx" : {
"enabled" : "true",
"domain" : "example.com"
}
}
}
}
YAML
infinispan:
cacheContainer:
statistics: "true"
jmx:
enabled: "true"
domain: "example.com"
5.2. Performing cross-site operations with JMX clients
Perform cross-site operations with JMX clients.
Prerequisites
- Configure Data Grid to register JMX MBeans
Procedure
- Connect to Data Grid with any JMX client.
Invoke operations from the following MBeans:
-
XSiteAdminprovides cross-site operations for caches. GlobalXSiteAdminOperationsprovides cross-site operations for Cache Managers.For example, to bring sites back online, invoke
bringSiteOnline(siteName).
-

5.3. JMX MBeans for cross-site replication
Data Grid provides JMX MBeans for cross-site replication that let you gather statistics and perform remote operations.
The org.infinispan:type=Cache component provides the following JMX MBeans:
-
XSiteAdminexposes cross-site operations that apply to specific cache instances. -
RpcManagerprovides statistics about network requests for cross-site replication. -
AsyncXSiteStatisticsprovides statistics for asynchronous cross-site replication, including queue size and number of conflicts.
The org.infinispan:type=CacheManager component includes the following JMX MBean:
-
GlobalXSiteAdminOperationsexposes cross-site operations that apply to all caches in a cache container.
For details about JMX MBeans along with descriptions of available operations and statistics, see the Data Grid JMX Components documentation.
